Could not find stored procedure 'sp_filestream_configure'.

I am trying to enable FILESTREAM for the database instance but I am getting the message "Could not find stored procedure 'sp_filestream_configure."

I have even done the required changes in the configuration manager like:

1.Enable FILESTREAM for Transact-SQL access

2.Enable FILESTREAM for File I/O streaming access

when I try :

EXEC sp_filestream_configure
? @enable_level = 3

I get the message "Could not find stored procedure 'sp_filestream_configure." Please help!!!
